CVE-2026-41729 Details
Description
Spring Data REST is vulnerable to SpEL expression injection through map-typed properties when processing JSON Patch (application/json-patch+json) requests. When a persistent entity exposes a Map-typed property, the JSON Pointer path segment used as the map key is embedded directly into a SpEL expression without sanitization or validation. Affected versions: Spring Data REST 3.7.0 through 3.7.19; 4.3.0 through 4.3.16; 4.4.0 through 4.4.14; 4.5.0 through 4.5.11; 5.0.0 through 5.0.5.
A vulnerability exists in Spring Data REST versions 3.7.0 through 3.7.19, 4.3.0 through 4.3.16, 4.4.0 through 4.4.14, 4.5.0 through 4.5.11, and 5.0.0 through 5.0.5. This vulnerability allows for SpEL expression injection through map-typed properties when handling JSON Patch requests. The issue arises because the JSON Pointer path segment used as the map key is directly incorporated into a SpEL expression without proper sanitization or validation. An attacker capable of sending PATCH requests to an affected endpoint can manipulate the map key to execute arbitrary SpEL sub-expressions within the context of the aggregate root, potentially exploiting both read and write patch paths.
Users should upgrade to Spring Data REST versions 3.7.20, 4.3.17, 4.4.15, 4.5.12 (OSS), or 5.0.6 (OSS).
